"Would not recommend if you haven't taken AP Chem. I tried my best to learn from the textbook readings and lectures, but it was tough to do the discussion questions. The lectures are a bit disorganized but engaging. Both professors are really kind and, contrary to what some people say, I think they’re actually pretty accessible. They respond quickly to emails and are very understanding. I went to a couple of office hours and it was only me there. "

"Supposed to be AP Chem review but the course is poorly organized and professors way too hard to access for office hours. They try their best to give subpar grades which pushes students to other STEM subjects, and just inconveniences anyone committed to the premed track."
